subscription.trial_converting
Trial about to convert.
When this fires
Fires 24 hours before trial_ends_at to give consumers a window to send conversion-reminder messaging. Emitted once per trial, by the hourly trial-conversion notifier.
Fires exactly once per trial, 24 hours before
trial_ends_at.
Caveats
- Idempotency is enforced server-side: each trial receives this event at most once.
- If
trial_ends_atis moved closer than 24h after the trial has already started, the notice may not fire.
